"Huge swathes of the interface are remarkable only by their familiarity: a home screen with a grid of apps; a single navigation button to take you back to this screen or alternatively to a multi-tasking screen by way of a long press; and a top-to-bottom pull-down for notifications and quick access to settings. It's basic, but it represents pretty much what all these new operating systems are supposed to be: ways of getting functionality that is at least close to Android but without all the licensing costs associated with running Google services." A lobotomised iOS/Android mashup. This is completely void of personality. Still, it looks like this is Samsung's future (guess who was wrong).

Firefox OS API will probably get more traction than Tizen Web API and it can be supported anywhere, including Android.

Firefox OS API is a subset of Tizen Web API. You code identically for both. Due to Tizen security the extra features of Tizen above Firefox OS API default have to be queried. So there is really no difference between writing a Firefox OS application and a Tizen Web Application.

Tizen is where Android and Firefox OS meet. Then there is Tizen own native on top.
